Yep. If you can do one pull up you can likely do 2 chin ups, so mix em up.
Scap pulls are also a good warm up so I’d do those first.
I’d then do a pull up or two if you can squeeze both out in good form.
Then I’d try one pull up every 2 mins (do other work in between like KB swings or core work etc)
Then try chins and get some assistance from your biceps.
Then finish off with some sets of controlled negs.
Get ready for DOMS!
